In a fistfight, I'm torn. Supes has the strength advantage, but Apoc has several other things over Supes, including total molecular control of his body, TP/TK, energy fields, energy weapons, energy absorbtion.......you know what? screw it. Apoc wins. curbstomp. Supes would get his energy drained, mind-raped, or Apoc would make some krytonite after finding out what it is from Superman's mind, or countless other ways.
